  2. VirtualBox in Windows 10 64-bit guest only shows 32-bit options

    My Situation

    I am running VirtualBox v5.2.32 on an Ubuntu 18.04 host. I have created a Windows 10 (64-bit) guest. I installed VirtualBox v6.0.10 in the Windows 10 guest (Windows 10 Pro - v1903 - 64-bit). I am trying to create an Ubuntu (64-bit) guest inside the Windows 10 guest. I only see 32-bit options inside the Windows guest. After several attempts to resolve this, I am still only seeing 32-bit options.

    My Intention

    The purpose for creating a VM inside a VM is to be able to ensure that VirtualBox is working so that I can test Vagrant configuration inside a Windows 10 environment. Our Vagrant config is using 64-bit base images, so I need to be able set up 64-bit guests inside this Windows 10 guest.

    What I Have Already Tried

    ...on the Ubuntu Host

    I have checked Enable VT-x/AMD-V on the System > Acceleration tab in the Ubuntu host's VirtualBox config for the Windows 10 guest machine.

    ...on the Windows Guest

    In the Windows guest machine, I can see that the host's physical CPU details are passed through in Settings > System > About and it shows as a "64-bit operating system, x64-based processor".

    This is a vanilla Windows 10 Pro installation, no additional software (i.e., no addon virus protection software).

    I inspected Windows Features to ensure that the following are not checked:

    • Guarded Host
    • Hyper V
    • Virtual Machine Platform
    • windows Hypervisor Platform
    • Windows Subsystem for Linux

    ...because my googleing seems to indicate that some or all of these might be an issue.

    Based on a VirtualBox forum (I have a 64bit host, but can't install 64bit guests), using gpedit.msc, I set Local Computer Policy > Computer Configuration > Administrative Templates > System > Device Guard > Turn on Virtualization Based Security to Disabled. I also check that Windows Security > Device Security > Core Isolation Details is set to Off.

    I have "repaired" the VirtualBox installation. I have uninstalled VirtualBox, rebooted, reinstalled, and then rebooted again.

    Related Stack Exchange Questions and Other References

    I looked at these related, previously asked questions and followed their suggestions as indicated in the steps above. Everything I am finding seems to be related to a Windows 64-bit host running directly on the host machine, not dealing with a Windows host which is itself a guest VM.

  4. Virtualbox will only show 32 bit options even though I have a 64 bit machine

    VirtualBox only allowing 32 bit OS

    When I start VirtualBox, I only have 32 bit operating systems available. After some research I followed the steps on another post but to no avail. My host OS is 64 bit, Intel Virtualization Technology and VT-d are both enabled in the BIOS, and Hyper-V platform is disabled in the Windows Feature list, yet I still only am presented 32 bit operating systems.

    I find these same instructions many places and they seem to solve the problem for everyone, but not for me.

    I also tried repairing the installation without luck. How can I fix this to run a 64 bit Linux OS in VB?

    EDIT I also have the latest version of BIOS.
